ATTACHING WINDOW -SHADES TO ROLLERS.

SPECIFICATION forming part of Letters Patent No. 484,962, dated October 25, 1892.

Application filed March 11, 1891. Serial No. 384,533. (No model.)

T0 at whom it may concern.-

Be it known that I, EDMUND F. HARTSHORN, a citizen of the United States, and aresident of the city of Newark,in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Attaching Window-Shades to Rollers, of which the following is a specification.

In the drawings, Figure 1 is a view of my improved fastening ready to receive the shade. Fig. 2 is a view of the fastening with the shade attached. Fig. 3 is a view of the fastening, together with the shade secured in position on the roller. Fig. 4 is a sectional view of Fig. 3 through the line 00 00.

My improved fastening device consists of a metal clasp constructed in two parts joined together, so as to receive and secure the edge of the shade between them and adapted to partially encircle and clasp the roller.

In the particular form of my improvement shown in the drawings, A and B are the two metal plates forming the clasp, arranged one on top of the other. These plates, which are shaped so as to conform to the surface of the roller, are connected together by the hinge h, which, as illustrated, is formed of a struck-up portion of one piece passing through the other piece and turned over to hold the two pieces together, and thus hinging the two pieces together in a manner that will limit the movement of the upper piece to a point below a vertical position, as illustrated in Fig. 1 of the drawings, so the plates can be opened or separated, as shown in Fig. 1, a sufficient distance to permit the edge of the shade to be inserted between them. By hinging the upper plate to the lower plate in a manner to limit its movement in the manner previously stated, one part is caused to offer a resistance to the movement of the other at such point, so that the upper plate is limited in its movement to such an extent that when the shade is pulled outward at an angle to the circumference of the roller when the clasp is applied to the roller the upper plate or leaf will not open far enough to allow the shade to be pulled out from between the two parts of the clasp. It will also be observed that the upper plate or leaf A extends to the rear of the lower plate B, so that it may lie against the surface of the roller, whereby when pressed down close to the roller the portion of it which lies upon the plate B will be forced or pressed down against the lower plate, and thus more securely hold the shade in place. What may be termed the outer or front edge of the upper plateA is provided with teeth a, which are bent slightly downward or inward, and which enter or project into corresponding openings 61 in the lower plate B when the two plates are brought close together. The hinge 72 may be of any construction and the plates A and B may be connected together in any manner, so that the teeth 0 can be raised above the under plate B sufficient to insert the shade. The clasp or plates A and B are attached to the roller by the spurs a and b on the plates A and B, respectively. These teeth are preferably on a prolongation a 1) some distance from the edge of the plates, as shown, so as to more completely encircle the roller and maintain a firmer hold on the latter, and the ends of the spurs are bent in to hook or bite into the roller. \Vhen the plates are clasped on or around the roller, they are spread out, which causes them to press close together and forces the teeth a into the openings d. The manner of attaching the shades is as follows: The plates are opened or separated, as shown in Fig. l, and the edge of the shade inserted between them. The plates are then pressed together, which causes the teeth 0 to pierce or penetrate the shade, as is shown in Fig. 2, and project into the openings (1. The clasp is then sprung onto the roller and the spurs a and I) forced into the latter, when the clasp will be firmly attached to the roller and securely held from turning on the latter. As the plates are spread apart when 011 the roller, as above described, the two plates are pressed close together, thus securely grasping the shade between them and holding the latter by the teeth 0. Then the shade is completely unwoun'd from the roller and the pull of the shade comes directly on the clasp, the grasp of the plates on the shade, aided by the teeth a, prevents the shade from being drawn out from between the plates, and thus being detached from the roller, and the spurs a b on each side of the clasp hold the latter in place on the roller and prevent it being turned in either direction on the latter by the force of the pull on the shade.

As will be seen, the shade is inserted until the edge is in contact with the hinge k, and thus the clasp forms a guide for the shade and insures it being attached to the roller evenly and in a straight line. These clasps may be of any length found convenient and any number of clasps may be used.

I do not wish to confine myself to the exact construction of the clasp shown, as the clasp may be varied in form and construction without departing from the spirit of my invention.

What I claim as new is- 1. In a fastening for attaching shades to rollers, the two pieces fastened together and lapping one upon the other to form jaws to receive and. retain the edge of a shade between them, said pieces being of substantiallycorresponding curvature to each other and thereby to press the jaws together to grasp and hold the shade between them, substantially as described.
